The DeKalb County School District's technology chief, Gary Brantley, said most of his system's student data has not been put on outside "cloud" computing networks yet.He said that is likely to change, though, as a generation of technology staffers retires and the district loses the expertise to operate its own computer servers.
Also, teachers are signing up students for online programs that are not vetted, he said.
There are free offerings for everything from math tutoring to monitoring of classroom misbehavior.

Brantley said he plans to ask the school board to tighten the policy for teachers.
"If we don't stop it, it's going to get out of control," he said.
